Place the motherboard on a clean, flat surface. Preheat your soldering iron. Each USB port has eight points of connection to the motherboard (pictured above). Using your soldering iron, apply heat to each solder joint in turn while pulling the USB port away from the board. Soldering irons can reach temperatures of over 500 degrees. Watch your fingers!
